The Ax60+ is a gas detection platform system using RS485 communications to allow the user to connect up to 4 sensor units to the central display.

Each sensor is factory configured at location one. If a system includes more than one sensor each one must be reconfigured by moving the jumper link to the appropriate sensor location, e.g., a system comprising 2 sensors has the jumper link fitted at sensor 1 location 1, sensor 2 location 2 and so on. Remove the cover to access the jumper link.

The sensors are connected to the central display unit in a 'daisy-chain' configuration as follows:

The first sensor in the chain is connected directly to the Ax60+ central display unit, wiring can either be via the 'knock-out' on the rear of the unit or the optional gland on the bottom of the unit

Any subsequent sensors in the 'chain' simply double-up the communications connections within each previous sensor unit as follows:

Alarm units for each sensor are connected within the relevant sensor at the 'strobe sounder' terminals

Again, if multiple alarm units are to be used, these should be daisy-chained in the same way as with multiple sensor units
